SLIDING-DOOR HANGER.

SPECIFICATION forming part of Letters Patent No. 511,208, dated December 19, 1893.

Application filed July 28,1893.

To aZ Z whom it may concern.-

Be it known that 1, PETER E. Ninson, a sub-v ect of the King of Sweden and Norway, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sliding-Door I-Iangers; and I do hereby declare the followmg to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in hangers for sliding doors or gates, of thekind in which the door is supported upon pivoted bars, and is adapted to be moved thereon parallel with the desired plane.

The invention has for its object to provide a hanger for a sliding door, upon which the door is adapted to be moved noiselessly, and to be operated with but little force, and which maybe readily adjusted and aligned when in position, and is also adapted to be made selfclosing.

I lVith this objectin view the invention consists 1n the novel combination, construction and arrangement of parts, hereinafter fully described, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of my improved sliding door hanger, with a portion of the door cut away to expose the construction and arrangement of the several parts, and in which the door is shown moved back or nearly opened. Fig. 2 is a front elevation with a portion of the door jamb cut away. Fig. 3 is a transverse section taken on the line 3. 3. of Fig. 1. Fig. at is also a transverse section taken on the line 4:. t. of Fig. 1. Fig. 5 is a vertical section of the adj ustment parts taken on the line 5. 5. of Fig. 1, and Fig. 6 is a diagram view showing the movement of the hangerbars in carrying the door in a parallel plane.

In the drawings, 1 designates the door, which is of the usual kind for dwellings, a pair being used for large spaces, and adapted to slide outward from between partitions, but which may be of any desired form or construction.

2 is a stud or post, adapted to' form a portion of the partition, and upon which the weight of the door is supported.

3 and 4, are bars pivotally connected to derial No. 481,750. (No model.)

gether at their center by means of the stud pin 5, and are adapted to give a parallel movement to the door when being opened or closed. The lower end of bar 3 is pivotally connected to the partition stud, by means of the pivot pin, 6. Said pivot pin is rigidly attached to the slide 7, and is adapted to be moved vertically therewith by the screw 8 tapped into said slide. Said screw is tu rned or revolved by the Worm gear wheel 9, and worm shaft 10. Said pivot pin is also adapted to be moved laterally, by means of the slide 11, and screw 12. Said slides, and the operating screws, are supported by the frame 13, rigidly secured to the partition stud.

14 is an adjustable stop, provided with a rubber cushion 15, for the bracket 16 attached to the back of the door to abut, or strike against in closing. Said stop is adjusted by means of the screwlT journaled in said frame. The outer ends of all of said adjusting screws are made square, and extend outward through the door-jamb, and are adapted to be turned by a socket wrench titted thereto, when the adjustment is required, the ends of the screws being otherwise covered by a molding. The upper end of the parallel bar 3, isprovided with a socket 1S, pivoted thereto, and which is adapted to slide upon the vertical bar 19 inserted therein, and which is fixedly held secured to the back edge of the upper end of the door by the bracket plate 20, rigidly attached to said door. The lowerend of the bar 4, is pivotally attached to theback edge of thelower end of the door by the plate 21, rigidly secured thereto, and the upper end of said bar is provided with a stud pin inserted therein, upon which the antitriction wheel or roller 22, is adapted to turn or revolve. Said wheel or roller, is held to move vertically, by contact with the slotted plate 23 rigidly secured to the partition stud.

24 is a spring bar or rod, adapted to be used when it is desired to make the door self-closing. The upper end of said spring bar is attached to the upper part of bar 3, and'the central portion is coiled around the central pivot stud connecting said parallel bars, while the other end of said spring rod is carried down and is connected to the lower part of bar 4, by the slide plate 25, to which it is secured,

and which is moved up or down upon said bar to adjust the spring to the desired tenslon for. closing the door, the adjustment belng secured by means of the set screw in said slide plate.

26 is a spiral spring, interposed between the upper end of the bar 3, and the sliding socket, to which said bar is pivoted, to prevent binding and to allow for any inaccuracy in the fittingup, or movement of the parts.

In the drawings, the door is shown to one sideof the space between the partitions, to accommodate the views to the size of the sheets. This is not necessary in practice and may be as desired.

The operation of the described parts, adapted for the support and movement of the door, will be clearly understood from an inspection of the drawings. The action of the support ing pivoted cross-bars, herein termed the parallel bars, and which are adapted to carry the door on a line or plane parallel with the floor, is shown in the diagram view Fig. 6, from which it is seen, that the door will be supported at the same height upon the pivot at- I It will be observed, that a salient feature of my invention, is the adjustment of the supporting pivot, the necessity for which, arises from the settling of the building and the wearing of the parts, the adjustment being also a matter of very great convenience in erecting and setting up the door, as both its height from the floor and line of travel can be readily changed as may be necessary. The removal of the door is provided for, by locating the screws securing the parts to the partition stud Where they can be taken out when the door is in position.

From the foregoing, it will be seen that the arrangement is one of great practical utility and adaptation. The door is easily moved and noiseless in its movement, and when made se1f-closing, the spring attachment is specially adapted for the purpose, the tension of the spring increasing as the angle between the bars becomes greater, and which gives a more nearly uniform resistance in opening the door.

I am aware that my invention is susceptible of'some modifications, in its practical application and details of construction, and I do not therefore desire to restrict myself therein, but claim the right to change the construction in each and every particular not at variance with the spirit of my invention.

Having thus described my invention, I claim 1. The combination in asliding door hanger, of a supporting pivot rigidly inserted in a vertical slide, said vertical slide adapted to slide upon a horizontal slide and to be moved therewith, and means adapted to move said slides vertically and horizontally, to adjust said sliding door, and. to fixedly secure and hold said slides when said door is ad usted, substantially as and for the purpose speci fied.

2. The combination with the described pair of pivotally connected parallel motion bars, one of which is pivotally attached at one end to an adjustable support and the other of which is pivotally attached at one end to the door, the opposite ends of both being held and adapted to move in a vertical plane in opening and closing the door, of a spring bar, one end of which is attached to one of said parallel bars, and the other end of which is attached'to an adjustable slide upon the other parallel bar, the central portion of said spring bar being coiled and looped around the connecting pivot of said parallel bars, substantially as and for the purpose specified.

3. In a door hanger and sliding door, the combination of an adjustable stop, adapted for the door to abut against, said stop provided with a rubber or yielding cushion, adapted to prevent the jar and noise in closing the door, said stop adapted to be adjusted when the door is hung and in a working position,

substantially as and-for the purpose specified.

4. In a door hanger. the combination comprising the parallel motion bars 3 and l-pivotally connected together at their center, the supporting pivot 6, inserted in the slide 7 and movable therewith, the screw 8, worm wheel 9 and worm screw shaft 10, adapted to move said slide and pivot vertically, the horizontal slide 11, and screw 12 adapted to move said pivot horizontally, the frame 13 rigidly screwed to the fixed partition stud 2 and adapted to form bearings for the adjusting screws, the adjustable stop 14, provided with the cushion 15, and adapted to abut against the plate 16, secured to the door, thescrew 17, adapted to adjust said stop, the socket 18 pivotally attached to one of said parallel bars and adapted to slide upon the bar 19, secured to the door by means of the plate 20, the bracket plate 21, secured to the door and pivoted to one of said parallel bars, the antifriction wheel or roller 22, pivoted to one of said parallel bars and adapted to slide upon the slotted plate 23, the spring bar 24, adjustable spring plate 25, and the spiral spring 26, interposed between the sliding socket and parallel bar, combined and arranged in the manner, and for the purpose substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
